BEABING.

specification of Letters Patent.

Paten ted June 22, 1920.

Application flled September 18, 1919. Serial No. 324,357.

T0 all 'whom it ma'/ emwern Be it known that I, LAMnnn'r H. VER- voon'r, a citizen of the United States.y residing nt New York city, in the county of New York and State of New York, haveinvented a new nd useful Bearing, of which the following is a specification.

The device forming the subject matter of this application is a roller henring. and one object of the invention is to lessen the frietion existing nt the ends of the rollers, anotherrohject being to provide a hearing in which a trnss-like action will he pro duced owing to the tupering of the rollers. a further object of the invention being to provide a structure wherein wear `is 'redured. The invention nims to provide a beuring which, may be adjusted without diflicnlty for the purpose of repairs, to provide a benring which Will operate with a minimum amount of grease. and to supply the bearing which will not run hot.

Typical embcdiments of the inve'ntion are shown in the drawing, hut. within the seope of what is claimed, changes fnllingg within the .skill of :1 rnerhanic maly ho made without dopartingr from the spirit.

In the 'awingsz- Fignre l shows in longitndinnl seetinn, a hearingf constrn:ted in m'corilanr'e with the invention Fig. 2 is ;L cross se'stion on the line -wti of Fig. 1;

Fig. il is a cross section on the line 3--3 of Fig. l;

Fig. 4 is a longitudinnl section showing a modificution;

Fig. 5 is a cross section on the line 5-- of Fig. 4;

Fig. 6 is a plan showing;I :i pair of the rollers and the ballsA which coact therewith;

Referring to the. forms shown in. Figs. 1, 2 and 3, there appcars a` sheft 1 having a tapered part 2 terminntingr in a 'tip 3 which is threaded as shown at 5. The shaft 1 is threaded as indicnted nt 4`` at the rear end of the tapercd part 2. 'The numeral 9 denotes a, sleeve having a tnpered bore 10 in which the part 2 of the shaft 1 is wedged by the action of a nut 7 and a lock nut 8 on the threaded tip 3. A nut on the threaded portion 4 of the shaft 1 may form an ahutment for the sleeve 9. The sleevo 9 has end flanges 11 provided with Shah low races 12.y the sleeve having an intermediate circumscrihing race, 14. Bells 15 coact with the races 12, halls 16 being received in the intermediate race 14.

Rollers 17 surround the sleeve 9 and hear thereon, the rollers taperingr toward their outer ends and being of frnsto eonical form. The rollers have spindles 18 received hetwcen the halls 16, the spindles conforming to the Shape of the hnlls so that the latter may receive the end thrust from the rollers. The rollcrs 17 are provided with spindles 10 received between thehnlls 15 and con' forming in Shape thereto, the halls 15 serving to take up' the end thrust from the rollers 17.

Casing members 20 and 21 are provided. these elements having eonienl snrfaces 25 eooperating with the rollers 17. The rasing member 21. includes nn end well 22 having` a wrench head 23 and an outstanding fiange 24. The casin member 20 is supplied with a flange 26 de ming an opening 27 through which the shnft 1..passes.

At 28 is shown a roi'ntahle or main menr her which may he a henrinif. ;i pnlley or n wheel of any kind.V depemling ujon whether the rahnft l rotates or is ixed. The missing members 20 and E1 are thw-zxded ;it *Z0- into he main member nut 711 is ihreade'i on the Pasirij; nwniher 13% unii e'zigngfw mi." side of the main m' *add-er ifiw. ;i nut iii) i" mg thrended on the easlng' member Q0 :lud 'en ga ing the other side of the element 28.

` Wing to the way in which the halls 15 nnd 1G are located with respect to the rollers V1',zend thrnst will he redufied to e ."ninimum and the rollers will have a truss like action in sustaining the parts with which they eoact.

In Figs. 4, 5 and 6, parts hereinhefore described nre designated by numerals previo'isly used, with the sulix '*a. The distin, 'uishin;r characteristics of this form of the invention are that the race 14 is omit ted, the sleeve, 0a having tapered or inelined sn' `ces 32 which coperate with the rollers 1771, nnd there being an intermediate rib 33 on the main member 28, the rib having n. race. 34 ret'kiving the balls 16.

In all forms of the invention, the rollers are so supported at their ends b the balls that longitudinal thrnst will be ta en care of ndeqntely. Any of the hearings shown may he taken down easly for repairs and will operate witli a minimum uinountof friction and .'ith u small amount of lubricunt.

at is claimed is:
